Abstract

Un códec de video recibe datos para un bloque de pixeles que han de ser codificados o decodificados como un bloque actual de una imagen actual de un video. El códec de video señaliza o analiza un primer elemento de sintaxis para un primer modo de codificación en un conjunto particular de dos o más modos de codificación. Cada uno de los modos de codificación del conjunto particular de modos de codificación modifica un candidato de fusión o una inter-predicción que se genera basándose en el candidato de fusión. El códec de video habilita el primer modo de codificación y deshabilita uno o más modos de codificación en el conjunto particular de modos de codificación. Uno o más modos de codificación deshabilitados en el conjunto particular de modos de codificación se deshabilitan sin analizar elementos de sintaxis para los modos de codificación deshabilitados. El códec de video codifica o decodifica el bloque actual al utilizar el primer modo de codificación habilitado y al pasar por alto los modos de codificación deshabilitados.
